SPECIFICATION forming part of Letters Patent No. 554,189, dated February 4, 1896.

Application filed April 22, 1895. Serial No. 546,712. (NonmdeL) To all whom, it may concern:

Be it known that I, SIRUS E. KocHENnAa FER, of Hollidaysburg, in the county of Blair and State of Pennsylvania, have invented a new and useful Improvement in Markers or Pens, of which the following is a specification.

My invention is an improved marker or pen especially designed for use in marking boxes or packages; and the invention consists in certain constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a side view, and Fig. 2 a longitudinal section, of a marker constructed according to my invention; and Fig. 3 is a cross-section on about line 3 3 of Fig. 2. Fig. 4 is a detail view showing the presser and pad.

The marker has a carrier or tube A, preferably provided at both ends with removable threaded caps 13 O, the cap B having at its extremity a drawn-in portion or flange 1) forming an annular bearing within which the spherical. piece 1) fits and beyond which it projects and forms the marking device.

A spring-actuated presser E operates within the carrier, and bearing against the spherical device tends to press the same outward so it is held normally projected and yet is yieldingly supported, this yielding arrangement of the spheres permitting pressure thereon to i11- crease or diminish the supply of the marking medium by effecting a compression of the absorbent pad, as will more fully appear hereinafter. This presser has at its lower end a dished head 6 fitting against the sphere D and a stem 6, the latter projecting into a suitable receiver F and engaging a spring f, as shown. This receiver is preferably supported upon the perforated diaphragm G. This diaphragm forms a back bearing for the pad H, which is of felt or other suitable absorbent material, and is arranged between the back bearing and the spherical point, so that pressure on such device may compress the pad and so increase the amount of marking fluid discharged on the device. This pad is held by the presser and is made annular with a central opening it fitting upon the stem 6 above the head e.

The marking fluid or other medium may be supplied in any desired quantity to the tube or casing and will pass into the pad, the lat ter operating as a plug to prevent the mark ing medium from passing too freely to the sphere and yet permitting the pressure upon such sphere to regulate the amount of marking fluid supplied.

In practice I prefer to make the sphere and its presser of hardened polished steel, the pad of felt and the spring of brass; but I do. not desire to be confined to any particular material or size, as the marker may be of any size, according to the size of the sphere or ball used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V 1. A marker comprising a supporting carrier or tube a sphere, a spring-actuated presser engaging such sphere and an absorbent pad held by the presser and in contact with the sphere the latter being movable bodily back against the pad whereby to compress the same substantially as shown and described.

2. A marker substantially as described com.- prising a tube or carrier a sphere a central presser and an annular absorbent pad surrounding such presser and in contact with the sphere the latter being movable bodily back against the pad whereby to compress the same substantially as set forth.

3. A marker comprising a tube or carrier a sphere yieldingly supported, an absorbent pad in contact with said sphere and a back bearing for said pad whereby thelatter may be compressed by pressure upon the sphere substantially as set forth.

4. A marker substantially as described comprising the tube or carrier provided with the perforated diaphragm, the spring-actuated presser, the sphere and the absorbent pad in contact with such sphere and fitting between the same and the diaphragm substantially as set forth.

5. The improved marker herein described consisting of the tube or carrier, the perforated diaphragm, the sphere, the spring-actuated presser engaging the same, and the annular absorbent pad held by the presser and arranged in contact with the sphere and between the same and the perforated diaphragm all substantially as and for the purposes set forth.
